<span>The area to be determined is a segment of the circle.

Since central angle is 120 degrees and 120/360 = 1/3
area of sector of circle is (1/3)*36pi = 12pi
For the area of triangle, you can split it into 2 30-60-90 right triangles with sides 3:3sqrt3:6
thus base of triangle is 6sqrt3 and height is 3

Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->
segment area = 12pi - 9sqrt3</span>

Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->

segment area = 12pi - 9sqrt3

I just did this so I know it's correct.

kow [346]

Answer:

32.99

Step-by-step explanation:(you might have to round) if you have to round it or.. but this is it because

236.40 divided by 24 is 9.85 so

325 divided by 9.85 is 32.99 (you only need 2 decimal places for these kinds of questions because of repeating decimals).

Hope this helps :)

What is the value of x

Nesterboy [21]

Answer:

$x = 2$

Step-by-step explanation:

First simplify the equation.

$\frac{7}{9}x -\frac{4}{9} =\frac{1}{4} +\frac{5}{12}$
$\frac{3}{9}x= \frac{3}{12} +\frac{5}{12}$
$\frac{3}{9}x=\frac{8}{12}$
$\frac{1}{3}x=\frac{2}{3}$

Now multiply both sides by 3.

$x = 2$

I hope it helps you. Please choose my answer as the BRAINLIEST.

Identify the slope and y-intercept of 3/5 - 1/3 x

Rudiy27

Your 3/5 - (1/3)x is an expression, not an equation. You must write out the entire equation in question:

"Identify the slope and y-int. of y = 3/5 - (1/3)x."

The y-intercept is obvious: It's 3/5.

The slope is (1/3).
